1.

Verify the TRACER 64x0 unit and the attached equipment are configured for the same line coding 
(B8ZS or AMI).

2.

Verify the cable connections for the T1 interface are solid.

All active E1 alarms are displayed on the 

 menu page. To identify 

the E1 interface in alarm and the specific alarm present, display the

 is an indication that the TRACER 64x0 may be unable to detect a viable E1 received 

signal from the connected E1 equipment. This error may be due to a degraded signal or no signal, or 
may be caused by improper framing.

1. Verify that the E1 cable is connected to the E1 interface on the TRACER 64x0.

2. Verify the connections at the opposite end of the E1 cable.

3. Verify that the framing mode (framed, multiframed, or unframed) is the same for both the

 

TRACER 64x0 and the E1 equipment.

A remote alarm (alarm indication signal or AIS) is generated by the attached equipment. The root 
cause must be determined at the attached equipment. A typical cause of a blue alarm is a lack of input 
to a CSU.

1.

Verify the input to any attached data equipment.

Line code violations (LCVs) indicate that the received E1 stream contains an invalid line code and are 
generally caused by an improper configuration or faulty wiring.

1.

Verify the TRACER 64x0 unit and the attached equipment are configured for the same line coding 
(HDB3 or AMI).

2. Verify the cable connections for the E1 interface are solid.
